In this article, we calculate the contributions of the vacuum condensates up to dimension-6 in the operator product expansion and study the masses and decay constants of the heavy tensor mesons 
, 
, 
, 
using the QCD sum rules. The predicted masses are in excellent agreement with the experimental data, while the ratios of the decay constants 
, where the exp denotes the experimental value.
